First oil change dealer put wrong engine oil.

I actually edited my post to reflect that before you quoted me, or at least before you hit the submit button.



Do you have more details on what the factory fill is?

Sorry I made an error in my response. Meant to state “it’s not ONLY what we get from the factory…”. I forgot the “only”.

But on that topic, I am a firm believer that we not only get from the factory the recommended 5w-30 semi synth SN+ Motorcraft, but with an additive/modifier to suppress the Coyote BBQ tick. I’d further speculate that it is XL17, essentially suspended carbon/graphite. To me this explains why it reappears after subsequent oil changes, but dissipates over time as carbon is reintroduced into the oil from whatever process (heat, blow by, etc.). It would be nice to have done an oil analysis that checks for soot (not a common test for gasoline ICE) on new delivery vehicle with almost 0 miles compared to virgin oil analysis.

I regret not getting a sample sooner than 1200 miles. I wanted to see what the starting viscosity numbers looked like. At 1200 miles, mine was under a 5w-30, at 9.1 (cSt 100C).

Me too, but I wish I would have done one right away and also have them measure soot to see if it may have added suspended carbon above a virgin oil sample. Measuring soot (suspended carbon) is not a common test for gasoline powered vehicles, it’s more available for diesel engines.

While it’s hard to track, it would be helpful to have a time series analysis mapping PPM of soot/carbon to incedence of BBQ Tick. And repeat after subsequent oil changes. Or have Ford come clean on what additives they use.

There’s numerous articles on the tribological benefits of suspended carbon in oil. Too much of too large a size can actually remove other beneficial additives like ZDDP (zinc phosphate). So while it may be better to have some carbon, it can be harmful to have too much.

And after all the unnecessary tips to get them to do thier jobs you're already paying for AND paying for all the oil and filter you bring with you, your Jiffy Lube oil change just cost you 3x as much.

Should you also offer to follow them home to mow thier lawns and do thier dishes?

just passing along a few tips that I use, trying to help. It has been my experience in life that it is extremely rare for people to “just do their jobs” for at least the past 15 years. Keeping a watchful eye on folks working on your pride and joy can keeps mishaps to a minimum.

@Bikeman315 ..... to follow your logic if the cause of the BBQ tick remains a mystery how do you know oil is not the cause? FYI The Ford dealer I take my Mustangs to (high volume Mustang seller) has not had one instance of BBQ tick (a too common phenomenon) when oil filters have been pre filled and the first and subsequent oil changes have been Ford FULL synthetic. Not one instance. You could hear the difference (quieter) when full synthetic was used my first oil change after factory fill.

@rijndael ..... nope. First, I'm not talking about "prior mustang coyotes" as that is irrelevant imo. There should be very little drop in viscosity or shear value if a decent oil is changed within the interval for use ie: daily driving, track, severe service. There is a huge difference between 5W20 and 5W30 and a massive gap between semi and full synthetic. Even aged full synthetics (if they have a decent base stock and decent VI added....Ford full synthetic is one) are vastly superior to semi synthetics as they build long chain polymers at a vastly superior speed when the engines internals are threatened by temperature spikes - which are common.

The have been hundreds of posts over the years with every conceivable combination of oil brands and types along with oil filters. There has never been any proven correlation to the tick and oil. What we have determined is that every Coyote has the tick. It’s part of the engine. The difference is in the volume. Some are quiet, some really noisy. The only way to reduce the volume on the noisy ones is Ceratec. Why? No one knows, for sure. Bottom line, the tick remains a mystery.

prefilling the filter does nothing. Been proven. If they don’t have the tick then they add ceratec or the ford additive. It has absolutely nothing to do with ford full synthetic or pre filling the filter. If it actually did this ford would say to use this and do that and not put out the service message about the tick being a characteristic of the engine.

Pre-filling may improve the amount of time it takes to build oil pressure. So without a pre-fill, there could be a couple second gap to build oil pressure. Whether or not it helps with BBQ Tick, didn't with mine. I always (for the past 45 years doing oil changes) pre-fill and used 10 qrts (not 9.5) 5w-30 Motorcraft Semi (not Full) Synth. Still got slight tick.

Here's one such video showing what happens without a prefill. Since it's one observation, I consider it informative but anecdotal. Skip to 9:18 to get to the observable test.

Thanks for saving me the time of posting that video.

If those mattered a significant amount, we'd have tons of UOA showing much higher wear with 5w20 vs 5w30, right? Can you show me those?

I never said there was zero difference. I'm saying that the sky isn't falling just because 5w-20 was put in. As I already mentioned, my 1200 mile UOA shows my 5w30 isn't even a 30w any more, at least as the 100C cSt is concerned.

And, I do think that 5w-20 is strictly a CAFE choice. The prior Coyotes, the ones you think don't matter here, would likely have never come with a 20w if it weren't for that. But, much like guessing at what the factory fill oil actually is, we will probably never know.

im not worried over 20 years of not doing it and knowing many car people who don’t and not once seeing any information that says to or you should. Only hearing some people have on forums. Plus you can’t even prefil on several vehicles because of the filter or angle of the filter.

That just means they can't avoid the added wear, as small as it may be, by not prefilling in vehicles with suboptimal filter housing designs. I wouldn't draw the conclusion that because some engine designs can't use that trick, no one should.

there is no data that shows not prefilling does any damage. You can do it if you want to have the warm and fuzzies. But that’s all it does. You do realize too every engine part should be coated in oil anyways and again it’s not a standard practice and it’s not anywhere that says you must or else.

Post 54 provided data. Where is yours?

If your argument is that the added wear is insignifican't, that's a different thing.
